Family law is a practice area concerned with legal issues involving family relationships, such as adoption, divorce, and child custody. Attorneys practicing family law typically handle divorce, child custody, child support, and other related legal matters. Some family law attorneys specialize in adoption, paternity, emancipation, or other matters usually not related to divorce. States have the right to determine “reasonable formal requirements” for marriage, including age and legal capacity, and the majority of states do not permit same-sex couples to marry (but this is a rapidly changing area of law). Likewise, state laws govern the various rules and procedures for divorce and other family law matters.
